- saagarjha 2y agoNot regularly but many languages have type systems that are algorithmically worse, like TypeScript
- 9dev 2y agoAs a user, I couldn’t care less about the algorithmic beauty of the type system if it works, lets me type complex things reliably, and is fast enough to stay out of my way. Does it do that by being a mess of duct table and plywood? Totally fine for me.
- saagarjha 2y agoSure, but often the duct tape and plywood makes it difficult to make things that are reliable and stay out of your way.
- troupo 2y agoAnd yet TypeScript doesn't fail with a cryptic nonsensical error just because you have the impossible component with an unfathomable number of two nested lists, like in SwiftUI.
- saagarjha 2y agoAlgorithmically worse doesn't mean worse in practice
- grandempire 2y agoCan you show a common line of type script that will take exponential complexity for typescript to resolve?
- saagarjha 2y agoI think you misunderstood my comment.
- troupo 2y agoEveryone misunderstood your reply. Perhaps it was a pure academic reply? Because reality always trumps theory.
- saagarjha 2y ago> Perhaps it was a pure academic reply Yes, exactly.
- grandempire 2y agoMy understanding is you are saying TypeScript has a similar complexity problem in its type system as Swift. I am wondering if you have a common example that would timeout or have problems. If not then I struggle to see what similarity you are seeing. (Genuine question, I am interested in what other languages do)
- saagarjha 2y agoNo, I'm saying it has a worse system than Swift's. The point I'm making is that they've designed things such that the normal case doesn't hit this, while Swift keeps adding APIs that exercise the worst of their type system.
